Abstract

A thermodynamic model was developed to describe the quasi-steady thermal process of a wide thin steel workpiece irradiated by a moving Gaussian laser beam. In this study, an experiment was done on six steels to verify this model. The calculated Ac1 and Ac3 depths and temperature cycles were compared with the measured results. For AISI 4340 steel, correction coefficients were applied to produce an empirical equation for temperature cycles above 488.4°C.
